This post will cover 10 ways to increase your SiteGround site’s speed.

1. SiteGround Is Slower By Default.

Based on our WordPress benchmarks, SiteGround is atleast 100-200 milliseconds slower for WordPress websites. I discovered this information after experimenting with SiteGround’s services for over two years.

Even a basic shared hosting such as GreenGeeks has an average TTFB of 311ms. At the same time, SiteGround recorded an average of 396ms for TTFB.

To further prove the stats, I invited 500 concurrent users to the website to track the time it took to respond. When GreenGeeks (77ms) and A2 Hosting (102ms) did a good job handling the load with ease, SiteGround required 173ms (lower response time is more efficient).

It’s unsurprising that SiteGround performance has suffered over the past few years following the sudden change to their hosting technology stacks.

They will push you to purchase premium plans to speed up your internet, such as this Ultra-Fast PHP feature to improve TTFB. This feature is only available on the Growbig and GoGeek plans. (Trivia We have tested this feature, and TTFB was still slow)

Solution: If you’re running binding sites, there are more suitable options than SiteGround. Even if you upgrade your site to Cloud-hosted SiteGround will not fix the speed problems. Moving your websites to one of the Fastest WordPress Hosting providers priced higher or lower than SiteGround.

2. Use SiteGround SuperCacher & SiteGround Optimizer

You can access the Site Tools and SuperCacher options to start. You can modify the settings.

Next, you’ll need to go to the WordPress dashboard and verify if the plugin SiteGround Optimizer has been installed within the plugin section.

Additionally, you can alter the front-end optimizations to improve performance and see if you notice an improvement in the site’s speed.

3. Try A Premium Caching Plugin

One way to improve the performance of your website is by using a premium Caching plugin.

SiteGround Optimizer could be a better plugin, and it is promoted to SiteGround users. It has a long history of conflicts with other plugins available.

Paragon Digital Marketing company which hosts more than 100 websites on SiteGround The company states that the plugin needs to be ready for production and then made available to users.

If WP Rocket has been developed and updated for 10 years, it is a new plugin to the industry. It must match WP Rocket for better results.

Try switching your plugin to WP Rocket and check for results.

4. Enable Cloudflare CDN

SiteGround provides the option of integrating Cloudflare utterly free of charge with all plans.

Cloudflare CDN has many advanced speed optimizations, such as reverse proxy caching, brotli Compression and script minification.

Cloudflare has a global network to deliver your website’s content to its intended audience from the nearest server.

Serving your website’s content to your intended audience from the closest server can significantly improve the speed of delivery of content and ultimately improve the user experience on your site.

5. Get Rid Of Unwanted Plugins

It’s always a good idea to determine whether you have any unneeded plugins or any plugins that could make your SiteGround WordPress site slow.

It’s important because such plugins can cause unnecessary weight to your website heavy and make your website slow.

If you’re wondering where to locate these plugins, it’s pretty easy.

In the beginning, look at the WordPress plugins section and check whether there is a plugin that isn’t working yet. If you discover a plugin, uninstall it as soon as possible.

To determine the plugins that affect your site’s performance, You can check your site using Gtmetrix.

After Gtmetrix examines your website, it is possible to access the Waterfall tab to find out what files are slow to load.

If you find any plugins in the files, it’s an indication that you should eliminate the plugins or find replacements.

After you have completed the necessary procedure, you need to examine your website using Gtmetrix again to determine if there’s any performance improvement.

If your changes are successful, you’ll undoubtedly notice improvements in the speed of your site.

6. Eliminate Unused CSS & JS

Another reason for slow loading on most websites is that they do not use CSS or JS.

In the majority of websites, using table plugins typically causes this issue. When you utilize Table plugins like Ninja Tables, the script loads on all pages. The script also loads on the Homepage, which can slow down the site.

You can stop the script from being loaded on pages you don’t want to, and that is where using a plugin such as PerfMatters is useful.

But, PerfMatters is a paid-for plugin. WP Asset Clean Up is an alternative to PerfMatters worth looking for. Both plugins allow you to disable scripts that are not needed on different pages.

On PerfMatters, you are able to navigate to a page and choose to disable scripts in the Script Manager’s top bar. Enabling scripts to load on specific pages will enhance the Core Web Vitals of your website.

7. Use Image Compression

Most websites employ images. However, ideas could make your site heavy and affect your site’s performance if you don’t improve the quality of your pictures.

It is, therefore, essential to reduce the size of images. The compression of images can speed up the speed of loading your site to a great extent.

There are two methods to accomplish this. One approach is to use WordPress plugins for image CDN, like WP Compress, which works via Google CDN and BunnyCDN.

Another way to accomplish this is to convert images to WebP format. There are a variety of free WordPress image optimization plugins that you can select from and then use to achieve this.

8. Use Delay JavaScript Execution

Another great way to improve website performance is to Delay JavaScript Execution. If you’re not comfortable with Delay JavaScript Execution.

In that scenario, it’s a great feature to hold off loading certain JavaScripts on the website that aren’t needed to load at the beginning of the time.

When users visit your websites Certain JavaScripts, such as Live chat widgets, Analytics scripts, or Facebook pixels, won’t start loading in the first few seconds.

The scripts will load after visitors reach the center of the page or hover over specific sections of the page.

WP Rocket comes with this feature, and using this feature will enhance the most comprehensive and content-rich paint.

9. Prefetch DNS Requests

Prefetch DNS Requests is a method to make external files load faster even when using a mobile network. The feature is accessible within WP Rocket.

You can search your website using Prefetch. Xyz to find more domains you could add to your Prefetch DNS request.

Adding domains to the Prefetch DNS requests will enhance the core web vitals of your website.

10. Speed Up the Site With PerfMatters

PerfMatters is among the most effective WordPress performance plugins. The plugin is light, with no JavaScript on the front end, which will speed up your website.

PerfMatters decrease HTTP requests and disable plugins, removes code, and optimizes databases to give users an understanding of how this plugin functions. Additionally, PerfMatters is compatible with other caching plugins.

11. Improve Site Speed With NitroPack

A different performance plugin is NitroPack. Based on Google data, NitroPack performs better speed optimization to help sites pass the Core Web Vitals score. It’s even more efficient than WP Rocket, as seen below.

NitroPack is a cloud-based, all-in-one speed Optimization plugin that integrates advanced caching and global CDN optimization of images and script minification. Utilizing NitroPack as a NitroPack WordPress plugin can significantly increase the speed of your site.

NitroPack is available as free as well as paid. I suggest using this plugin as it can be used for free for websites that get about 5000 monthly visitors. Large websites can proceed using NitroPack premium plans.
